Need advise for a Joule Thief with 20ma 1,2v power source

[ikram85]

Thank you very much to all of you, the first one works pretty well, we are learning pretty well how these amazing circuits work, I'm going to try this one, maybe it glows more, I'll use 1M ohm then, thank you all again

could it be even smaller? wow, it's fantastic, looks very efficient I'm going to try also this one without dying, thx

ikram85,

This is a more powerful JT that runs from a 9 Volt battery. This circuit will give
good light output from the 9 Volt battery until the battery is drained down to
approx. 6 Volt.

The attached circuit works a little better than my first version of this circuit.
